Sorry for re-opening an OLD thread ... and sorry for English reply - but I have an answer.

I found this while looking for a guide to do the same thing.

Set up :

Standard DM8000 (which only has a DVI port not a HDMI) running OpenPli 7.3

Sony Bravia TV (2019 model that does CEC HDMI)

Pulse-eight CEC HDMI usb plug

On the command line install the CEC utils:

opkg install libcec

The kernel driver that turns the HDMI CEC codes (via a fake serial port) into something you can read is not loaded.

you can see this by doing

ls -l / dev / ttyACM *

You will see no devices

We need to load a module from the kernel. So look in:

ls -l /lib/modules/3.2-dm8000/kernel/drivers/usb/class/

And we see

cdc-acm.ko

you can load this by doing

modprobe cdc-acm

now you should see a dev / ttyACM0 (or similar)

running:

cec-client

will now find the device and show you the commands from the remote (example press the yellow key):

DEBUG: [ 41565] key pressed: F4 (yellow) (74) current(ff) duration(0)

Now a fairly easy script will find these lines and turn them into command in the DM8000.

I couldn't find a direct way of entering commands so I used the webif system.

It is already setup that if you are coming from 127.0.0.1 it will allow commands without logging in.

I ran the web pages through NetTools and caught the remote control codes and turned them into a script.

So as an example - you press 'yellow' and this happens :

"F4(yellow)")

;;

*** It works ***

if anyone wants the script, let me know and I'll publish it
